The range of EMT machines covers the following ranges of performance:

• Typical maximum flowrates from 10 to 5000 kg per hour
• Downstream system pressures to 10 bar (depending on fluid type).  EPS pumps can be fitted for pressure-raising up to 200 bar.
• Rotational speeds typically 200 rpm maximum
• Typical motor power from 0.25kW to 15kW
• Stainless steel wetted parts or polymer/steel combinations for abrasive materials
• ATEX and UL hazardous area options
• Hygienic design options to 3A and EHEDG guidelines

Although closely-self-wiping, co-rotating (CSCO) twin screw extruders have been available for many years, they have traditionally been seen as "exotic" and expensive due to their reliance on precision for high performance applications.  However, for many powder feeding and pre-blending applications, accuracy is less important than cost control, simplicity and reliability.  The EMT fills the need for a simple, robust twin screw feeder and pre-blending paste mixing using the advantages of the CSCO design.  Unlike other forms of twin screw extruder, CSCO's self-wiping action ensures reliable feeding of sticky materials and inhomogenous mixtures which providing a degree of blending action.

The trade-off is that CSCO machines cannot develop high pressures, so Maelstrom solves this problem by fitting an EPS single screw pump to the EMT outlet to obtain a pressurised output for further processing.  This combination provides a powerful and flexible solution for inline powder-liquid blending and pumping applications.
